SHADE-HOLDER.

ZPECIFICATION forming part of Letters Patent N0. 767,313, dated August9, 1904.

Application filed February 9, 1903.

To @ZZ wle/0m t may concern,.-

Be it known that I, EDGAR A. RUSSELL, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inShade-Holders, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to improvements in shade-holders, its object being,among other things, to provide a one-piece shade-holder that can beeconomically constructed and readily attached and detached.

To these and other ends my invention consists in the shade-holderconstructed substantially as hereinafter described, and moreparticularly pointed out in the claims.

Referring to the drawing, which is a side elevation, partly in section,of my new and improved shade-holder, I have illustrated the same asbeing attached to the socket of an ordinary incandescent lamp.

This shade-holder is preferably made from sheet metal and provided witha socket-collar l, having threads thereon which engage the threads uponthe shank 2 of the lamp-socket 3, and a threaded shade-collar 5,connected with the collar 1 by a flaring iiange 4. The flange 4 can beeither solid or perforated by apertures 6 of any desired form. Withinthe interior of the collar 5 is threaded the head 7 of the shade 8. 4

In my improved shade-holder there is but one piece, the use of alladditional parts being dispensed with, and the threaded engagement ofthe holder with the lamp-socket and the shade with the holder provide aquick and convenient means of attaching' and detaching, them. y

By the use of a spun thread, as shown, the collar can be threaded intoor onto the lamp socket and shade.

Serial No. 142,460. (No model.)

I do not desire to be limited to the particular form of shade-holdershown,as the variety of forms in which my invention can be made isalmost endless, and I Would therefore have it understood that I do notlimit myself to the exact construction herein shown.

What I claim as new, and desire to secure by Letters Patent, is-

l. A shade-holder constructed of asingle piece of metal of uniformthickness thrfoughout and having two coaxial annular collars ofdifferent diameters and located one above the other, with adownwardly-flaring iange connecting the bottom of the upper collar withthe top of the lower collar, each of said collars having a spun -threadthereon, whereby it may be secured internally or externally,substantially as shown anglglescribed.

2. A shade-holder constructed of a singleVK jecting thread, whereby thecollars may be secured internally or externally, each of said collarsbeing of dierent diameters, coaxial with each other, and joined by acircular ange connecting the inner ends thereof, substantially as shownand described.

3. The combination with alamp-socket; ofa shade-holder constructed of asingle piece of sheet metal of uniform thickness throughout,

said shade-holder .being constructed with an internally `-and externallythreaded annular collar upon each end thereof; and a flange connectingthe inner ends of said collars, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
